Consumer review by: Tanto (



got another one to replace a crxppy MS bluetooth keyboard that has been nothing but trouble since day one. I think after four years of dealing with crxp it is time to say goodbye since the F keys quit working altogether on it. I prefer wired devices so...

solid keyboard, keys have good springs in them, and i am using this same brand, model to type this except this one is about 6 years old. it has never given me any trouble

buying keyboards that are junk in the first place

Best Standard Keyboard


Wrist rest is nice, but not everybody uses one. It doesn't have any multimedia/shortcut buttons but I honestly don't use them and I couldn't justify that as a con.

This is a solid, quiet keyboard ; Next to mechanical keyboards (Rosewill, Das) and the discontinued Logitech Elite keyboard (the one with the spinning volume control) this is my favorite keyboard of all time

Wasn't cheaper. Doesn't make the familiar click-clack noise of the old IBM Model Ms
